This study presents a novel strategy for NMR chemosensors by utilizing self-assembled cavity structures on silica nanoparticles. These nanohybrids demonstrate selective detection of physiologically relevant compounds through STD-based NMR experiments.
We report a strategy for the realization of NMR chemosensors based on the spontaneous self-assembly of lower rim pyridinium-functionalized tetraphopshonate cavitands on commercial silica nanoparticles. These nanohybrids enable the selective detection of physiologically relevant N-methylated amines, with a limit of detection of 31 mu M, via STD-based NMR experiments, achieving for the first time fine structural selectivity in nanoparticle-assisted NMR chemosensing.
